Let's start with the basic sine function<span>, f(t) = </span>sin<span>(t). This </span>function<span> has an amplitude of 1 because the graph goes one unit up and one unit down from the midline of the graph. This </span>function<span> has a </span>period<span> of 2π because the </span>sine<span> wave repeats every 2π units</span>

Answer:
D) 3x + 15 ≥ 300
Step-by-step explanation:
The rectangle must have a area of AT LEAST 300 square ft, or 300 or greater. Use the greater than or equal sign: ≥ 300.
Note that your are solving for the area, and that this shape is a rectangle. To get the area of the rectangle, simply multiply length and width:
(3) * (x + 5) = Area of rectangle.
Distribute the 3 to all terms:
3(x + 5) = 3x + 15 = Area of rectangle.
Put the two parts together:
3x + 15 ≥ 300.
